I chose it by choosing the size of the switch and the magnitude of the current that can correspond to the small depth. The drop in voltage after installation was also less, it was a very good switch performance.

Because the switch broke down, when we asked the manufacturer for repair, we requested 2000 yen business trip repair 13000 yen at parts cost. When I looked for broken parts with a monotail, it cost about 1,200 yen for shipping fee cash on delivery fee but it became possible to repair. In the future I would like to search by monotalaw and then request repair.
